D266 Hardfacing Welding Electrode
GB/T 984 EDMn-B-16
Suitable for hardfacing impact-prone and wear-resistant parts such as various crushers, high manganese steel rails, buckets, and bulldozers.
A high manganese hardfacing electrode with low-hydrogen potassium coating. The deposited metal is austenitic high manganese steel, featuring work hardening, toughness, and wear resistance. The addition of Mo enhances crack resistance and wear performance.
AC, DC reverse polarity (AC, DC+)

1. Drying requirement: Electrodes must be baked at 300～350℃ for 1 hour before use and used immediately after baking.
2. Use low current and narrow weld beads during hardfacing.
3. When hardfacing high manganese steel workpieces, remove the fatigued layer, perform water toughening treatment, or use chromium-manganese steel electrodes (e.g., D277) for backing.
4. Significant yellow fumes are generated during hardfacing; ensure strong ventilation and operate from upwind positions.
